Nursing Elites

1. Insulin glargine (Lantus) is prescribed for a client with diabetes mellitus. The nurse tells the client that it is best to take the insulin:

• A. 1 hour after each meal
• B. Once daily, at the same time each day
• C. 15 minutes before breakfast, lunch, and dinner
• D. Before each meal, based on the blood glucose level

Correct answer: B

Rationale: Insulin glargine (Lantus) is a long-acting insulin with a duration of action of approximately 24 hours, making it suitable for once-daily dosing at the same time each day. This regimen helps maintain consistent blood glucose levels and simplifies the client's treatment routine. Taking insulin glargine once daily provides basal insulin coverage throughout the day, reducing the risk of hypoglycemia compared to short-acting insulins that are taken before each meal.

2. A client taking ethambutol (Myambutol) understands the instructions provided by the nurse if the client states that he or she will immediately report:

• A. Impaired sense of hearing
• B. Problems with visual acuity
• C. Gastrointestinal (GI) side effects
• D. Orange-red discoloration of body secretions

Correct answer: B

Rationale: The correct answer is B: Problems with visual acuity. Ethambutol is known to cause optic neuritis, leading to a decrease in visual acuity and color discrimination. Therefore, any visual changes should be reported promptly to prevent further complications. Choices A, C, and D are incorrect because ethambutol does not typically cause impaired sense of hearing, gastrointestinal side effects, or orange-red discoloration of body secretions. It is crucial for clients taking ethambutol to be aware of potential visual disturbances and report them promptly to healthcare providers.

3. A nurse is monitoring a client receiving lithium carbonate for bipolar disorder. Which finding should the nurse report immediately to the healthcare provider?

• A. Increased thirst
• B. Fine hand tremors
• C. Frequent urination
• D. Persistent vomiting

Correct answer: D

Rationale: Persistent vomiting can be a sign of lithium toxicity, which requires immediate medical attention. Increased thirst, fine hand tremors, and frequent urination are common side effects of lithium.

4. Mafenide acetate (Sulfamylon) is prescribed for a client with a burn injury. When applying the medication, the client complains of local discomfort and burning. Which of the following is the most appropriate nursing action?

• A. Notifying the registered nurse
• B. Discontinuing the medication
• C. Informing the client that this is normal
• D. Applying a thinner film than prescribed to the burn site

Correct answer: C

Rationale: The correct action is to inform the client that local discomfort and burning are normal reactions to Mafenide acetate. This medication is used to treat burns by reducing bacteria in avascular tissues. Discontinuing the medication or applying a thinner film than prescribed is not necessary or recommended in this situation.

5. A client who is receiving digoxin (Lanoxin) daily has a serum potassium level of 3.0 mEq/L and is complaining of anorexia. A healthcare provider prescribes a digoxin level to rule out digoxin toxicity. A nurse checks the results, knowing that which of the following is the therapeutic serum level (range) for digoxin?

• A. 3 to 5 ng/mL
• B. 0.5 to 2 ng/mL
• C. 1.2 to 2.8 ng/mL
• D. 3.5 to 5.5 ng/mL

Correct answer: B

Rationale: The therapeutic serum level for digoxin ranges from 0.5 to 2 ng/mL. This range is considered optimal for therapeutic effects while minimizing the risk of toxicity. Levels above 2 ng/mL may lead to digoxin toxicity, which can manifest as anorexia among other symptoms. Therefore, the nurse should be vigilant in monitoring the digoxin levels to ensure the client's safety and therapeutic effectiveness of the medication.
